i have played the game for like 2 years and what ever montsh since 07 01 2012

sometimes, yes. depends on the command and what you are doing.

what do i need for beyond unzippering ?? i has used it soo rarely i dont even remember downloading it to point i downloaded it twice

you don't need to open winrar, just rightclick the file you want to unpack and click "extract here", then winrar will automatically unpack it

at times, yes

would it be safer if some one just team viewed me and did it for me ???

if your machine is not powerful enough to handle such encounters (and trust me, most people on these forums machines can't handle it), yes it could crash your entire machine (and I have seen certain game files become "corrupt" after having a game running and my computer making an unexpected reboot over my years of gaming)

fine ill limit it to 15 but im sure my computer can handle it .-. i have ram and memory its brand new computer well few months old still under warranty i mean i guess i could buy a stronger CPU and graphics card but i dont have $400.00 atm to cover maybe in a few monthss
